CHARLES \V. SLEEPER, OF ISLAND POND, VERMONT.

CAN FORMING AND SOLDERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 429,872, dated June 10,1890.

Application filed January 28, 1889. Serial No. 297,876. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES WV. SLEEPER, a citizen of the United States,residing at Island Pond, in the county of Essex and State of Vermont,have invented a new and useful Machine for Seaming and Forming theBodies of Tin Cans, of which the following is a specification.

My invention relates to improvements in seaming-machines in which thecan-bodies are automatically formed about a cylinder or series ofcylinders supplied with solder and flux and automatically soldered.

The objects of my invention are, first, to prepare the edges ofcan-bodies for soldering by rolling them smooth and to proper shape andcoating them with a liquid flux; second, to provide means for feedingeach can-body to one of a series of forming devices; third, to providemeans for forming the can-bodies about an adjustable cylinder, leavingthe overlapping edge exposed, so that it may be soldered; fourth, todeposit a quantity of powdered resin upon the overlapping edge or seamof the can-body; fifth, to carry the canbody from point to point throughthe several operations; sixth, to deposit the required amount of solderupon the seam; seventh, to solder the seam; eighth, to expel thefinished can-body from the machine. I accomplish these objects andprovide means for automatically operating the several devices by meansof the mechanism illustrated in the accompanying drawings, in whichsimilar letters and figures refer to similar part-s throughout theseveral views.

My invention consists in the combination of a device for feeding sheetsof tin, a device for feeding and cutting solder, a carryingwheel, and aforming device, (for each of which I have made separate application forpatents in the United States,) with a resin-feed, soldering-irons, andmeans for supporting and automatically operating the several devices,described in detail, as follows:

The device for feeding sheets of tin for which I obtained a patent, No.393,082, November 20, 1888, and which will be. referred to hereinafteras the tin-feed, is constructed as follows: Abed a is provided withslots 1 1 and two adjustable sides a a adjustably'secured to the bed aby suitable bolts fitted to. the slots 1 1. Two guides a a secured to,the bed a, serve as ways for a sliding block a which carries a cross-bara, the ends of which are forked, so as to grasp and push the tinforward. Two rests a a serve to support the tin, and two sets of guidesa a guide the tin while it is being put into position to be fed forward.Two rollers a (d serve to crimp the end ofthe sheet that is to be theoverlapping edge of the seam, and at the same time roll the said edgesmooth. Two rollers a a serve to roll the edge that is to be the underedge of the seam smooth and flat. A guide (0 guides the tin below thecylinder of the forming device and is secured to the tin-table (0 Thetimtable a is used to hold the sheets of tin, and is supported by twouprights a a. A finxing device a is secured to the side a in such mannerthat the crimped edge of the tin shall pass through it in its forwardmotion and receive a coating of liquid flux, which is fed to the fluxingdevice a, through the tube a, from an ordinary sight-feed lubricator a.

As means for operating the tin-feed I have provided teeth upon the underside of the sliding block a to engage with two gears a a, the axles ofwhich work in suitable bearings secured to the bed a. A rack (1)", heldin position by two guides a (L engages with two pinions a a which aresecured to the gears a a The effect of the motion imparted by the rack ato the pinions a (W is to cause the sliding block a to move in theguides a from one of the gears a to the other, the motion of the slidingblock being greater than the motion of the rack a in proportion as thegear a is to the pinions (L23. A roller 2 is secured to the rack a andworks in a slot in the lever a which lever is pivoted upon the bolt 3 tothe arm or bracket a, which is secured to the frame A of the machine.The lower end of the lever a carries a roller which works in the groovedcam (L22 upon the shaft A I have also provided a bracket a), to whichthe bed a is secured. The bracket (L25 is secured to the frame bysuitable bolts 4 4: 4 4;, which pass through slots in the said bracket.The bracket e is raised and lowered by means of the screw 5, and securedin such position that the tin asit leaves the feeding device willentertheforming device properly.

The forming device for which I have made separate application forapatent, No. 295,454, dated January -1,1889, is best shown in Figs. 9,10, 11, and 12, and is described as follows: A work-plate Z), secured tothe gear 15 of carrying-wheel by a bolt B is provided with a slot 6,fitted to a projection upon the hub of the gear 13. Two rectangularslots (1 (one of which is shown in Fig. 2) are provided to allow asuitable fork or ejector to pass through the work-plate a to push thefinished canbody off from the cylinder. The cylinder Z) is secured tothe work-plate b by the bolt 13", and is provided with two slots 7 7,and is slightly flattened on its lower side. A bracket b supporting twoclamps b b, is secured to the work-plate b by suitable screws. Theclamps Z)" Z)" act to form the can-body (a sheet of tin cut to size toform the body of a can) about the cylinder.

To adjust the size of cans, I have provided a false piece 8, fitted tothe cylinder I), and an auxiliary piece 9, fitted loosely to the bracketb and held upward by a spring 10. The diameter of the can is increasedby inserting pieces of metal between the piece 8 and the cylinder 1).

A bracket L supports two locking-arms I) b, pivoted upon the screws 1111 and connected by the toggle-joint W. The arms I) b are provided withgrooves or slots 12, Fig. 11,

and the cars 13 of the clamps b b" are provided with studs 14, carryingrollers which work in the slots 12 of the locking-arms. The clamps b bare closed about the cylinder b by the forked piece U, which in risingto the posit-ion shown by corresponding dotted lines strikes the clampsU h and carries them up and forces them about the cylinder, the rollers15 and 16 working against the clamps. The clamp I) is closed first asthe roller 16 passes closer to the cylinder than the roller 15. Theclamp b is finally closed by the projection b" striking the pin 17 ofthe togglejoint and forcing it up past its center. The yoke bimmediately descends after closing the clamps to allow the wheel to makeits motion. The studs 18 18 and block 19, which act as guides to thefork I), are secured to and made a part of the frame A.

To automatically operate the forming device, I have provided abracket 1) which is secured to the frame A and serves as a support forone end of a lever I), the other end being connected to the fork Z1 bythe connecting-rod I1 The lever I) is moved by an arm (J (upon the shaftA carrying a roller 1), which at each revolution of the shaft A strikesthe lever b and moves it to the position shown by corresponding dottedlines.

The resin-feed (best shown in Figs. 1 and 19) is described as follows: 0is a box or hopper to hold a quantity of powdered resin. A corrugatedroll 0' passes through the lower part of the resin-box 0. Upon one endof the roll 0 is a ratchet 0 An arm 0 carries a pawl c to engage withthe ratchet c and a roller 0", the arm 0 being fitted loosely to the endof the roll 0' in such a manner thatits weight shall cause it to fall tothe position shown in Fig. 1. Two adjusting pieces 0 c are secured tothe sides of the resin-box c by suitable screws, which pass throughslots in the said adj listing-pieces. The resin-box c is secured to thearm c". An arm 0 is clamped to the stationary shaft 13' and serves as abearing for a rock-shaft c upon which the arms a and c" are placed. Acam 0 similar in shape to cam f acts upon the arm 0 by means of thecam-rod 0 causing the resinbox to rise and fall as required. As theresin-box descends, the roller 0'' strikes the flange or back of thetin-table a, and the pawl 0 engaging with the ratchet 0 causes theroller 0' to rotate within the resin-box c and by rotating to carry alittle resin between the adjusting-piece c and the roll 0, the amount ofresin fed being determined by the space between them. The piece c set toscrape off any resin that may adhere to the roll a. The resin thus feddrops through the opening 25, which is made to coincide with the openingbetween the edges of the clamps of the forming device.

The carrying-wheel, for which I have made separate application for apatent, Serial N 0. 270,996, dated April 17, 1888, is described asfollows, Figs. 2, 3, and 4; The wheel or flange B is fitted loosely to astationary shaft B, and is provided with a number of hubs or bosses Bequidistant from each other and from the shaft B. The wheel B is alsoprovided with bosses B placed at equal distances from each other andfrom the shaft B. The drawings Show six each of these bosses; -but anynumber may be used, if required. A gear 13 is keyed to the shaft B.Gears B are fitted loosely to each of the bosses B, the hubs 26 of thesaid gears, Fig. 10, being of sufficient length to pass through thebosses B and are bored through their centers to receive the bolts 13*,by which the formingdevices are secured to the said gears. The hubs Bare provided with project-ions which fit the slots or recesses 6 in thework-plate I) of forming device and prevent the said work -plates fromturning upon the bolt B Intermediate gears B upon the studs B (whichproject from the face of the wheel B) connect each of the gears B withthe stationary gear B The wheel B has an intermittent motion about theshaft B, each step of the said motion being equal to a completerevolution divided by the number of bosses B. The gears B and B are ofthe same pitch and diameter, and, as the gear B is keyed to upon theshaft B.

the stationary shaft B and does not revolve, it follows that the gears Bdo not rotate upon their axis, but revolve about a common center withoutchanging their position in relation to the horizon, carrying the seriesof forming devices which are secured to each of the gears 13 To supportand operate the carrying-wheel I have provided the following mechanism,viz: The shaft B rests in two clamp-boxes B B which are secured to thestandards A A which are bolted to the frame A. The standard A isprovided with a horizontal bar or girt A A cam 7t, upon the shaft Agives motion to a lever h, which is provided with a roller to work inthe said cam. The lever h is pivoted to a bracket 45, which is securedto the frame A. A connecting-rod h connects the lever h with anoscillating arm h A pin 27 is fitted loosely to-the extremity of the arm7L3. One end of the pin 27 is fitted to the hubs, projections,

or bosses B which are bored to receive the said pin. The motion of thearm if is adjusted to carry the pin 27 back and forth through the are 27B stopping an instant at each extremity of the arc. The pin 27 has agroove across it to receive the end of a lever It", Fig. 4, which issecured to the arm 71 by a bolt 28. I

The lever h is operated by a slide h, resting upon the standards A A andguided by rectangular grooves in the boxes B E the said slide beingprovided with two projections or fingers 29 30, which grasp theballshaped end 31- of the lever h". A block h is secured to the slide7L5 by suitable screws,

' andis provided with a latch-pin 7L7, which is made fast to the saidblock and passesloosely through the guide 7B. The end of latchpin 71. isturned to fit the holes in projections B The slide 71,5 and latch-pin hare given an alternating backward and forward motion by the cam 7t,which acts upon a roller in the cam-rod h which is attached to the arm hby the stud 32. The arm h works upon a stud 33, and is provided with aroller that is grasped between the projections 34 35 of the block 7L6.

Inoperation, the arm it being in the position shown in Fig. 2, the slideh and latchpin 7L7 move forward, the latch-pin 72 entering one of theprojections B and thus looking the wheel B in position. At the same timethe finger 29 moves the lever 71 and causes it to withdraw the pin 27from the projection B The arm 71. then moves, carrying the pin 27through the are 27 B when the return motion of the slide 7r forces thepin 27 into the projection B and at the-same time withdraws thelatch-pin W. The arm h in its return motion carries the wheel B with it,the operation being repeated with each revolution of the shafts A A.

The device for feeding and cutting solder, for which I have madeseparateapplication for a patent September 5, 1888, Serial No. 284,604,and which will be called the solder feed when referred to hereinafter,is best shown in Figs. 1, 2, 3, and 1S, and is described as follows;

To a bed-piece d is secured a knife (1'.

Two sides (1 d are secured to the bed d. An

ear 22 projects from the bed d to receive the end of a connecting-rod,by which the device is given an oscillating motion about the pin 23. Thesides d d areprovided with bearings for the feed-rolls d d", thecutting-roll (1 and the carrier-roll d. Slots d are provided to guide aspindle, upon which a roll of sheet or ribbon solder d is wound. Thefeed-rolls d d, which grasp and feed the solder, are provided with gears20 21, which engage each other and-are operated by the ratchetd andpawlcarryinglever (1 An adjustable stop d acts upon the lever (P at eachoscillation of the device and causes the ratchet d to move. Thefeed-roll d is held down by adjustingscrews 24 24. The cutting-roll d isoperated by an arm or crank (Z A connecting-rod (Z connects the arm (1with a quadrant d, by which the position ofv the cutting-edge of thecutting-roll d is adjusted. motion of the device causes the cutting-rolld to move, so as to leave a space betweenits cutting-edge and the knifed as the device rises and to close the space as it descends.

The solder is fed between the cutting-edge of The oscillatin A andconnected the same to the car 22 by a rod (1 and stop (Z The oscillationof the solder-feed should be sufiicient to allow the forming devices topass beneath the same when it is raised to its highest point.

To automatically solder the can-bodies, I have provided twosoldering-irons e c, of wroughtiron or mild steel of box shape, and tobe heated by blowing a flame into them. The soldering-irons are held byarms 6 which are provided with openings or slots 46, through which thefaces 36 of the soldering-irons project. The soldering-irons are notfastened to the arms 6 but are simply dropped into the slots 46 in thesame, and may be readily removed or changed while hot. The arms 9 areattached to the forked lever e by studs 37 37, the lever 6 beingprovided with slots 38 for adjusting the height of the arms e The levere is pivoted upon the pin 39 in a standard 6', which is secured to theshaft B. The soldering-irons are given a reciprocating or rubbinghorizontal motion (similar to the motion of the hand in soldering) by acam e upon the shaft A acting upon the cam-rod e, which is provided witha roller to work in the groove in said cam, and is connected to the arme by the stud 40. The arms e rest upon the extremities of the forkedlever 6 and are guided by the lips 41 upon the same. The lever e ispivoted upon the pin 42 in the standard a which is secured to the shaft13. The lever e acts to automatically raise and lower thesoldering-irons at regular intervals, as required, by the motion of thecarryingwheel, and is operated by a cam e upon the shaft A connected tothe lever e by the camrod e which is provided with a roller to work inthe groove of the said cam and a slot -t3 for adjusting the position ofthe lever e by means of the stud 44.

To automatically open the clamps of the forming devices, I have providedan arm f, Figs. 7 and 17, with afingerf at one extremity, and carrying aroller upon the end f to work in the groove of a cam f 3 upon the shaftA The arm f is supported by a stud f, which is secured to the frame A.At the proper time the cam f causes the arm f to move about the stud f"until the finger f strikes the pin 17 of the toggle-joint b of theforming device and pulls it down, causing the upper ends of thelocking-arms to separate and partly open the clamps, in which positionthe clamps are held until the finished canbody is removed, when the armf is moved back to its former position and the clamps fall open by theirweight.

To automatically eject the can-body after it is soldered, I haveprovided a forked piece or ejector g, Figs. 1, 2, and 3, working insuitable guides and moved by a lever g, which is supported by a bracket9 and acted upon by a cam 9 upon the shaft A The motion is so arrangedthat the instant that the clamps of the forming device begin to open theejector g moves forward, the forked end passing between the arms of thegear and through the slots I1 I) of the work-plate and 7 7 of thecylinder, forcing the finished. can-bod y oil? from the cylinder andreturning to its former position in time to allow the carrying-wheel tomove.

A rectangular frame A serves to support the several devices, and isprovided with suitable bearings for the shafts A A and A, of which theshafts A and A carry the cams necessary to operate the movable parts ofthe machine.

The machine is driven by a belt to the clutch-pulley A upon the shaft A.Thepulley A is made to engage with the clutch A by the shipper A",operated by the hand-lever A A pinion A upon the shaft A engages with agear A upon the shaft A. The shafts A A are geared together by evengears A A. A hand-wheel A upon the shaft A is provided to operate themachine by hand when adjusting any of the parts.

In operation the can-bodies are placed upon the tin-table a, and fromthence they are placed by hand one at a time upon the rests a a. Thecross-bar a moves the can-body from its position upon the rests a, a, tothe forming device. The ends of the can-body are prepared for solderingas the body moves forward by passing between the rollers a a and a a"(by which they are rolled smooth and to proper shape) and through thefiuxing device, where the end that is to be the overlapping edge of theseam receives a coating of liquid flux. The body is then automaticallyformed about the adjustable forming-cylinder, the overlapping edge beingexposed between the edges of the clamps. The resin-feed descends anddeposits a little powdered resin upon the seam and returns to its formerposition in time to allow the carrying-wheel to turn without strikingit. The carrying-wheel makes one motion or step, which brings theforming device with the said can-body beneath the solder-feed, where astrip of solder is cut from the roll of ribbon-solder and deposited uponthe seam. The second motion of the carrying-wheel brings the formingdevice containing the said can-body beneath the solderingiron e, whichdrops upon the seam and, by imitating as nearly as possible the handmotion of soldering, melts the solder and solders the two edges of thecan-body together. The third motion of the carrying-wheel brings theforming device containing the said can-body beneath the secondsoldering-iron e, where the operation of soldering is repeated. Theobjcct of two soldering-irons is to reduce the liability to imperfectwork and to increase the capacity of the machine by keeping the seammelted longer than could be done with one soldering-iron. The fifthmotion of the carrying-wheel brings the said forming device in positionto be operated upon by the fingerf of the arm j, which pulls down thetogglejoint b and thus partly opens the clamps. The ejector gthen slidesforward and pushes off the can. The sixth motion of the carrylng-wheelbrings the forming device in position to receive a second can-bod y, theclamps falling wide open while the carrying-wheel is in motion. 5

In the above description I have followed one can-body and one formingdevice only through a complete revolution of the carrying- Wheel. Itwill be understood, however, that the series of forming devices followeach other, and all'the several operations are repeated with each, sothat a can-body is formedand soldered at each step of thecarrying-wheel.

The forming devices may be removed from the carrying-wheel by removingthe bolt B and larger or smaller forming devices applied, in which casethe sides a a of the tin-feed will require adjusting to the length ofthe can-body and the whole tin-feed raised or lowered to the properheight to guide the tin to the forming device. The soldering-irons willalso require adjusting to position, the slots 38 43 and studs 37 44being provided for the adjustment.
